So I have to ask...is there *any* documentation out there on what this
is and how people are supposed to use it?  Shockingly, typing "Google
fibers" into Google leads to a less than fully joyful outcome...  This
won't be easy for anybody to review if they have to start by
reverse-engineering what it's supposed to do.
